The scope of Nuki Hub is to have an efficient way to integrate Nuki devices in a local Home Automation platform.
The Nuki Hub software runs on a ESP32 module and acts as a bridge between Nuki devices and a Home Automation platform.
It communicates with a Nuki Lock and/or Opener through Bluetooth (BLE) and uses MQTT to integrate with other systems.
It exposes the lock state (and much more) through MQTT and allows executing commands like locking and unlocking as well as changing the Nuki Lock/Opener configuration through MQTT.
Nuki Hub does not integrate with the Nuki mobile app, it can't register itself as a bridge in the official Nuki mobile app.

Supported ESP32 devices:
- All ESP32 models with WIFI and BLE which are supported by Arduino Core 2.0.15 should work. Tested builds are provided for the ESP32, ESP32-S3 and ESP32-C3.
- Untested builds are provided for the ESP32-Solo1.
Not supported ESP32 devices:
- The ESP32-S2 has no BLE and as such can't run Nuki Hub.
- The ESP32-C6 and ESP32-H2 are not supported by Arduino Core 2.0.15 and as such Nuki Hub is not compiled against these targets (at this time).
Supported Nuki devices:

Supported Ethernet devices:
As an alternative to Wi-Fi (which is available on any supported ESP32), the following ESP32 modules with wired ethernet are supported:
- Olimex ESP32-POE
- Olimex ESP32-POE-ISO
- WT32-ETH01
- M5Stack Atom POE
- M5Stack PoESP32 Unit
- LilyGO-T-ETH-POE
Note for users upgrading from Nuki Hub 8.21 or lower:
Please go to "MQTT and Network Configuration" and select "Wi-Fi only" as the network device (unless you use other network hardware).
Flash the firmware to an ESP32. The easiest way to install is to use the web installer using a compatible browser like Chrome/Opera/Edge:
https://technyon.github.io/nuki_hub/
NOTE: Webflash is not available for the ESP32-Solo1
Alternatively download the latest release for your ESP32 model from https://github.com/technyon/nuki_hub/releases
Unpack the 7z archive and read the included readme.txt for installation instructions for either "Espressif Flash Download Tools" or "esptool".
Power up the ESP32 and a new Wi-Fi access point named "ESP32_(8 CHARACTER ALPHANUMERIC)" should appear.
Connect a client device to this access point and in a browser navigate to "http://192.168.4.1".
Use the web interface to connect the ESP to your preferred Wi-Fi network.
After configuring Wi-Fi, the ESP should automatically connect to your network.
To configure the connection to the MQTT broker first connect your client device to the same Wi-Fi network the ESP32 is connected to.
In a browser navigate to the IP address assigned to the ESP32 via DHCP (often found in the web interface of your internet router).
Next click on "Edit" below "MQTT and Network Configuration" and enter the address and port (usually 1883) of your MQTT broker and a username and a password if required by your MQTT broker.
The firmware supports SSL encryption for MQTT, however most people and especially home users don't use this.
In that case leave all fields starting with "MQTT SSL" blank. Otherwise see the "MQTT Encryption" section of this README.
Enable pairing mode on the Nuki Lock or Opener (press the button on the Nuki device for a few seconds) and power on the ESP32.
Pairing should be automatic.
When pairing is successful, the web interface should show "Paired: Yes" (it might be necessary to reload the page in your browser).
MQTT nodes like lock state and battery level should now reflect the reported values from the lock.
Note: It is possible to run Nuki Hub alongside a Nuki Bridge.
This is not recommended and will lead to excessive battery drain and can lead to either device missing updates.
Enable "Register as app" before pairing to allow this. Otherwise the Bridge will be unregistered when pairing the Nuki Hub.

Possible values for the node per setting are "unchanged", "noValueSet", "invalidValue", "valueTooLong", "accessDenied", "success", "failed", "timeOut", "working", "notPaired", "error" and "undefined"
Example:
{"advertisingMode":"success","general":"success"}
If Home Assistant discovery is enabled (see the Home Assistant Discovery section of this README) Nuki Hub will create entities for almost all of the above settings. These entities will be disabled by default in Home Assistant, but can be found in the MQTT devices section of the Home Assistant UI under the "Configuration" section of the Nuki Lock/Opener and enabled there.
After the initial installation of the Nuki Hub firmware via serial connection, further updates can be deployed via OTA update from a browser.
In the configuration portal, scroll down to "Firmware update" and click "Open".
Then Click "Browse" and select the new "nuki_hub.bin" file and select "Upload file".
After about a minute the new firmware should be installed afterwhich the ESP will reboot automatically.
The communication via MQTT can be SSL encrypted.
To enable SSL encryption, supply the necessary information in the MQTT Configuration page.
The following configurations are supported:
CA, CERT and KEY are empty -> No encryption
CA is filled but CERT and KEY are empty -> Encrypted MQTT
CA, CERT and KEY are filled -> Encrypted MQTT with client vaildation
This software supports MQTT Discovery for integrating Nuki Hub with Home Assistant.
To enable autodiscovery, supply the discovery topic that is configured in your Home Assistant instance (If you have not changed this setting in Home Assistant the default is "homeassistant") in the MQTT Configuration page.
Once enabled, the Nuki Lock and/or Opener and related entities should automatically appear in your Home Assistant MQTT devices.
The following mapping between Home Assistant services and Nuki commands is setup when enabling autodiscovery:
Smartlock | Opener (default) | Opener (alternative) | |
---|---|---|---|
lock.lock | Lock | Disable Ring To Open | Disable Continuous Mode |
lock.unlock | Unlock | Enable Ring To Open | Enable Continuous Mode |
lock.open | Unlatch | Electric Strike Actuation | Electric Strike Actuation |
NOTE: MQTT Discovery uses retained MQTT messages to store devices configurations. In order to avoid orphan configurations on your broker please disable autodiscovery first if you no longer want to use this software. Retained messages are automatically cleared when unpairing and when changing/disabling autodiscovery topic in MQTT Configuration page.
NOTE2: Home Assistant can be setup manually using the MQTT Lock integration, but this is not recommended
If a keypad is connected to the lock, keypad codes can be added, updated and removed. This has to enabled first in the configuration portal. Check "Add, modify and delete keypad codes" under "Access Level Configuration" and save the configuration.
Information about current keypad codes is published as JSON data to the "keypad/json" MQTT topic.
This needs to be enabled separately by checking "Publish keypad codes information" under "Access Level Configuration" and saving the configuration.
For security reasons, the code itself is not published.
To change Nuki Lock/Opener keypad settings set the keypad/actionJson
topic to a JSON formatted value containing the following nodes.
Node | Delete | Add | Update | Usage | Possible values |
---|---|---|---|---|---|
action | Required | Required | Required | The action to execute | "delete", "add", "update" |
codeId | Required | Not used | Required | The code ID of the existing code to delete or update | Integer |
code | Not used | Required | Required | The code to create or update | 6-digit Integer without zero's, can't start with "12" |
enabled | Not used | Not used | Optional | Enable or disable the code, always enabled on add, disabled if not set on update | 1 = enabled, 0 = disabled |
name | Not used | Required | Required | The name of the code to create or update | String, max 20 chars |
timeLimited | Not used | Optional | Optional | If this authorization is restricted to access only at certain times, disabled if not set (requires enabled = 1) | 1 = enabled, 0 = disabled |
allowedFrom | Not used | Optional | Optional | The start timestamp from which access should be allowed (requires enabled = 1 and timeLimited = 1) | "YYYY-MM-DD HH:MM:SS" |
allowedUntil | Not used | Optional | Optional | The end timestamp until access should be allowed (requires enabled = 1 and timeLimited = 1) | "YYYY-MM-DD HH:MM:SS" |
allowedWeekdays | Not used | Optional | Optional | Weekdays on which access should be allowed (requires enabled = 1 and timeLimited = 1) | Array of days: "mon", "tue", "wed", "thu" , "fri" "sat", "sun" |
allowedFromTime | Not used | Optional | Optional | The start time per day from which access should be allowed (requires enabled = 1 and timeLimited = 1) | "HH:MM" |
allowedUntilTime | Not used | Optional | Optional | The end time per day until access should be allowed (requires enabled = 1 and timeLimited = 1) | "HH:MM" |
Examples:
- Delete:
{ "action": "delete", "codeId": "1234" }
- Add:
{ "action": "add", "code": "589472", "name": "Test", "timeLimited": "1", "allowedFrom": "2024-04-12 10:00:00", "allowedUntil": "2034-04-12 10:00:00", "allowedWeekdays": [ "wed", "thu", "fri" ], "allowedFromTime": "08:00", "allowedUntilTime": "16:00" }
- Update:
{ "action": "update", "codeId": "1234", "code": "589472", "enabled": "1", "name": "Test", "timeLimited": "1", "allowedFrom": "2024-04-12 10:00:00", "allowedUntil": "2034-04-12 10:00:00", "allowedWeekdays": [ "mon", "tue", "sat", "sun" ], "allowedFromTime": "08:00", "allowedUntilTime": "16:00" }
The result of the last configuration change action will be published to the configuration/commandResultJson
MQTT topic.
Possible values are "noPinSet", "keypadControlDisabled", "keypadNotAvailable", "keypadDisabled", "invalidConfig", "invalidJson", "noActionSet", "invalidAction", "noExistingCodeIdSet", "noNameSet", "noValidCodeSet", "noCodeSet", "invalidAllowedFrom", "invalidAllowedUntil", "invalidAllowedFromTime", "invalidAllowedUntilTime", "success", "failed", "timeOut", "working", "notPaired", "error" and "undefined".
If a keypad is connected to the lock, keypad codes can be added, updated and removed. This has to enabled first in the configuration portal. Check "Add, modify and delete keypad codes" under "Access Level Configuration" and save the configuration.
Information about codes is published under "keypad/code_x", x starting from 0 up the number of configured codes. This needs to be enabled separately by checking "Publish keypad codes information" under "Access Level Configuration" and saving the configuration.
For security reasons, the code itself is not published. To modify keypad codes, a command structure is setup under keypad/command:
- keypad/command/id: The id of an existing code, found under keypad_code_x
- keypad/command/name: Display name of the code
- keypad/command/code: The actual 6-digit keypad code
- keypad/command/enabled: Set to 1 to enable the code, 0 to disable
- keypad/command/action: The action to execute. Possible values are add, delete and update
To modify keypad codes, the first four parameter nodes have to be set depending on the command:
- To add a code, set name, code, enabled **
- To delete a code, set id
- To update a code, set id, name, code, enabled
** Note: Rules for codes are:
- The code must be a 6 digit number
- The code can't contain 0
- The code can't start with 12
After setting the necessary parameters, write the action to be executed to the command node. For example, to add a code:
- write "John Doe" to name
- write 111222 to code
- write 1 to enabled
- write "add" to action
Time control entries can be added, updated and removed. This has to enabled first in the configuration portal. Check "Add, modify and delete time control entries" under "Access Level Configuration" and save the configuration.
Information about current time control entries is published as JSON data to the "timecontrol/json" MQTT topic.
This needs to be enabled separately by checking "Publish time control entries information" under "Access Level Configuration" and saving the configuration.
To change Nuki Lock/Opener time control settings set the timecontrol/actionJson
topic to a JSON formatted value containing the following nodes.
Node | Delete | Add | Update | Usage | Possible values |
---|---|---|---|---|---|
action | Required | Required | Required | The action to execute | "delete", "add", "update" |
entryId | Required | Not used | Required | The entry ID of the existing entry to delete or update | Integer |
enabled | Not used | Not used | Optional | Enable or disable the entry, always enabled on add, disabled if not set on update | 1 = enabled, 0 = disabled |
weekdays | Not used | Optional | Optional | Weekdays on which the chosen lock action should be exectued (requires enabled = 1) | Array of days: "mon", "tue", "wed", "thu" , "fri" "sat", "sun" |
time | Not used | Required | Required | The time on which the chosen lock action should be executed (requires enabled = 1) | "HH:MM" |
lockAction | Not used | Required | Required | The lock action that should be executed on the chosen weekdays at the chosen time (requires enabled = 1) | For the Nuki lock: "Unlock", "Lock", "Unlatch", "LockNgo", "LockNgoUnlatch", "FullLock". For the Nuki Opener: "ActivateRTO", "DeactivateRTO", "ElectricStrikeActuation", "ActivateCM", "DeactivateCM |
Examples:
- Delete:
{ "action": "delete", "entryId": "1234" }
- Add:
{ "action": "add", "weekdays": [ "wed", "thu", "fri" ], "time": "08:00", "lockAction": "Unlock" }
- Update:
{ "action": "update", "entryId": "1234", "enabled": "1", "weekdays": [ "mon", "tue", "sat", "sun" ], "time": "08:00", "lockAction": "Lock" }
The lock can be controlled via GPIO.
To enable GPIO control, go the the "GPIO Configuration" page where each GPIO can be configured for a specific role:
- Disabled: The GPIO is disabled
- Input: Lock: When connect to Ground, a lock command is sent to the lock
- Input: Unlock: When connect to Ground, an unlock command is sent to the lock
- Input: Unlatch: When connect to Ground, an unlatch command is sent to the lock
- Input: Lock n Go: When connect to Ground, a Lock n Go command is sent to the lock
- Input: Lock n Go and unlatch: When connect to Ground, a Lock n Go and unlatch command is sent to the lock
- Input: Electric strike actuation: When connect to Ground, an electric strike actuation command is sent to the opener (open door for configured amount of time)
- Input: Activate RTO: When connect to Ground, Ring-to-open is activated (opener)
- Input: Activate CM: When connect to Ground, Continuous mode is activated (opener)
- Input: Deactivate RTO/CM: Disable RTO or CM, depending on which is active (opener)
- Input: Dectivate RTO: When connect to Ground, Ring-to-open is deactivated (opener)
- Input: Dectivate CM: When connect to Ground, Continuous mode is deactivated (opener)
- Output: High when locked: Outputs a high signal when the door is locked
- Output: High when unlocked: Outputs a high signal when the door is unlocked
- Output: High when motor blocked: Outputs a high signal when the motor is blocked (lock)
- Output: High when RTO active: Outputs a high signal when ring-to-open is active (opener)
- Output: High when CM active: Outputs a high signal when continuous mode is active (opener)
- Output: High when RTO or CM active: Outputs a high signal when either ring-to-open or continuous mode is active (opener)
- General input (pull-down): The pin is configured in pull-down configuration and its state is published to the "gpio/pin_x/state" topic
- General input (pull-up): The pin is configured in pull-up configuration and its state is published to the "gpio/pin_x/state" topic
- Genral output: The pin is set to high or low depending on the "gpio/pin_x/state" topic
Note: The old setting "Enable control via GPIO" is removed. If you had enabled this setting before upgrading to 8.22, the PINs are automatically configured to be compatible with the previously hard-coded PINs.
If you prefer to connect to the MQTT Broker via Ethernet instead of Wi-Fi, you either use one of the supported ESP32 modules (see about section above), or wire a seperate Wiznet W5x00 Module (W5100, W5200, W5500 are supported). To use a supported module, flash the firmware, connect via Wi-Fi and select the correct network hardware in the "MQTT and Network Configuration" section.
To wire an external W5x00 module to the ESP, use this wiring scheme:
- Connect W5x00 to ESP32 SPI0:
- W5x00 SCK to GPIO18
- W5x00 MISO to GPIO19
- W5x00 MOSI to GPIO23
- W5x00 CS/SS to GPIO5
- W5x00 SCK to GPIO18
- Optionally connect:
- W5x00 reset to GPIO33
- W5x00 reset to GPIO33
Now connect via Wi-Fi and change the network hardware to "Generic W5500".
If the W5500 hwardware isn't detected, Wi-Fi is used as a fallback.
Note: Encrypted MQTT is only available for Wi-Fi and LAN8720 modules, W5x00 modules don't support encryption
(that leaves Olimex, WT32-ETH01 and M5Stack PoESP32 Unit if encryption is desired).
If encryption is needed, Olimex is the easiest option, since it has USB for flashing onboard.
Unfortunately the ESP32 has problems with some access points and reconnecting fails.
As a workaround you can navigate to "MQTT and Network Configuration" and enable "Restart on disconnect".
This will reboot the ESP as soon as it gets disconnected from Wi-Fi.
Also, this reduces the config portal timeout to three minutes to prevent the ESP being stuck in config mode in case an access point is offline temporarily.
If this still doesn't fix the disconnects and the ESP becomes unreachable, the "Restart timer" option can be used as a last resort.
It will restart the ESP after a configured amount of time.
First, make sure the firmware version of the Nuki device is up-to-date, older versions have issues pairing.
Next, try erasing the ESP32 flash and then (re-)flash the firmware.
To erase the flash, use the espressif download tool and click the "Erase" button.
Afterwards flash the firmware as described in the readme within the 7z file.
Also, there are reports that the ESP32 "DEVKIT1" module doesn't work and pairing is not possible. The reason is unknown, but if you use such a module, try a different one.
Reported as working are:
- M5Stack ATOM Lite
- ESP32-WROOM-32D (DEVKIT V4)
- ESP32-WROOM-32E
- ESP32-S3-WROOM-1
For more information check the related issue: technyon#39
Also, check that pairing is allowed. In the Nuki smartphone app, go to "Settings" --> "Features & Configuration" --> "Button & LED" and make sure "Bluetooh Pairing" is enabled.
A note about the M5Stack PoESP32 Unit. Here the initial Bluetooth reception is very poor (range less than one meter). The reason is that the module does not have an antenna on the PCB, but only an IPEX connector. By retrofitting an external SMA antenna (IPEX, or other names U.FL, IPAX, IPX, AMC, MHF, UMCC), bluetooth/Wifi works over several meters.
Make sure you are using at least version 2023.8.0 of Home Assistant.
The Home Assistant developers have made changes to MQTT auto discovery which break support for older version and Nuki Hub has adopted these changes.
This unfortunately means that older versions of Home Assistant are not supported by the Nuki Hub discovery implemenation anymore.
According to Nuki this is by design and part of the specification of the Pro lock.
You can use either the built-in Wi-Fi or a Bridge (which Nuki Hub registers as).
Using both at the same time is not supported.
Some functionality is restricted by the Lock (or Opener) firmware and is only accessible when the PIN is provided.
When setting up the lock (or opener), you have to set a PIN in the Nuki smartphone app.
Navigate to the Nuki Hub Credentials page, enter this PIN and click save.
See the previous point, this functionality needs the correct PIN to be configured.
Make sure the "Unlatch" option is checked under "Access Level Configuration".
Unlatching can be triggered using the lock.open service.
Alternatively an "Unlatch" button is exposed through Home Assistant discovery.
This button is disabled by default, but can be enabled in the Home Assistant UI.
When controlling two locks (or openers) connected to two ESPs, both devices react to the same command. When using Home Asistant, the same status is display for both locks.
When using multiple Nuki devices, different paths for each device have to be configured.
Navigate to "Nuki Configuration" and change the "MQTT Nuki Smartlock Path" or "MQTT Nuki Opener Path" under "Basic Nuki Configuration" for at least one of the devices.
This often is a result of enabling "Register as app".
Doing so will cause Nuki Hub to constantly query the lock and as such cause excessive battery drain.
To prevent this behaviour, unpair Nuki Hub, disable "Register as app", and re-pair.
Never enable "Register as app" unless you intend to use a Nuki Bridge in addition to Nuki Hub!
Docker (Preferred)
See the README in the Docker directory for instructions on building using Docker.
VMWare image (Not preferred, not using the latest Arduino ESP32 release at this time)
A virtual machine (VMWare image) that is setup to compile Nuki Hub is available for download at:
https://drive.google.com/file/d/1fUVYHDtxXAZOAfQ321iRNIwkqFwuDsBp/view?usp=share_link
User and password for the VM are both "nuki" and "nuki".
The source is checked out at ~/projects/nuki_hub, the cmake build directory is build.
To compile, run the following commands:
cd projects/nuki_hub/build
ninja
To upload the image via serial port, run:
ninja upload-nuki_hub
The serial device is defined in ~/.bashrc (Environment variable SERIAL_PORT), which you'll eventually have to adopt to your device.
